Thor shows warning when command line exit with error.
Implement class method to resolve.

$ ./bin/candy_check foo
Could not find command "foo".
Deprecation warning: Thor exit with status 0 on errors. To keep this behavior, you must define `exit_on_failure?` in `CandyCheck::CLI::App`
You can silence deprecations warning by setting the environment variable THOR_SILENCE_DEPRECATION.

@jnbt Please look this 😉

@tomorrowkey There is already another PR #59 which removes the explicit version dependency completely which I don't really like.

I have at least one project stuck at thor < 1.0, but your changes seems to be fully backwards compatible.

So maybe we could use a slightly more relaxes version requirement, e.g. < 2.0?

OK. It is better for us.
I'll change the version specification right away.

[tomorrowkey]

I changed version specification by git amend.
And added a test for .exit_on_failure? to keep testing coverage at 196073e

@jnbt Please review again
